I don't understand your question
Dropping two objects and seeing them hit the ground at the same time
Where everything is effected by a force
Answer: If the gravitacional acceleration is 1/6 of Earth's gravitational acceleration, it means that moon's gravitational acceleration is less than Earth's. Also, if the gravitational acceleration is less than Earth's, the astronaut's weight decreases since we calculate it multiplying his body mass by the gravity in the place given.
On Earth, an astronaut that is 70kg weights 70kg * 9.8 m/s² = 686N
On the Moon, the same astronaut would weight 70kg * 9.8 m/s² * 1/6 = 114,3 N
So, the astronaut’s weight decreases because the moon’s gravitational acceleration is less than Earth’s.
